This question arose in recent board meetings as the board began thinking about and discussing whether OFO should work more pro-actively in the area of conservation, especially as it relates to birds and their habitat. We realized that we, the board, were not exactly sure just who our members are and how they view OFO as an organization. To answer these questions we decided to take advantage of our connection to the Department of Sociology and Anthropology at Linfield College to develop the first ever membership survey. Our thanks to Tom Love and especially to Jeff Peterson, Ph.D. Associate Professor of Sociology, and his Social Research Methods class. And, our thanks to the 230 OFO members who took the time to respond to the survey! What are we learning? The board has not received the final report which we hope to publish in a future issue of Oregon Birds. There is strong agreement that OFO is doing a pretty good job with our core activities and strong agreement that we should include conservation issues in our future plans. The board is looking forward to the complete report that will help to shape our policy discussions and decisions over the next several years. OFO is also pleased to represent the Oregon Birding Community in recognizing and thanking our neighbors who have the great good luck to have a rare bird visit their yard and who then welcome birders to visit their homes and neighborhoods to enjoy these rare visitors. Pamela Johnston <[email protected]> has volunteered to coordinate nominations of people who deserve recognition for graciously welcoming birders to their homes and yards. If you know someone who deserves recognition, please send Pam a note, providing information -- name and address or phone number and any special remarks you would like to see highlighted in the thank you certificate. Also, let Pam know if you have a good photo of the bird that you would like to share to be used on the certificate. Our thanks to Pam for volunteering. OFO is nothing except for the volunteers who keep it going. Here are a few more folks who help make OFO strong: Good-host nominations: Pamela Johnston; OFO Birding Weekends: Ray Korpi ([email protected]); OFO Bookcase: Lucy Biggs ([email protected]); OREGON BIRDS: Production & Distribution: Sylvia Maulding ([email protected]), Anne Heyerly ([email protected]) and Don DeWitt ([email protected]); Editors: Steve Dowlan ([email protected]), Don DeWitt and Laura Graves; Membership: Anne Heyerly Yes, some of these folks are doing double duty! There's always room for more volunteers, so let us know if you'd like to help. Our thanks to everyone who cheerfully volunteers their time to help OFO succeed! Oregon Birds 29(1): 3, Spring 2003 Memories with LeRoy Fish: the man who did not fit in a box Matthew G. Hunter, 2205 NW 13th St. Corvallis, OR 97330, [email protected], 541-752-4604 LeRoy Fish died at home, on the morning of Wednesday, March 20, 2002. He just went out to the barn to do chores and his wife Jackie found him a while later in the shop. He was being treated for congestive heart failure. Many intellectual endeavors of man seek to put reality in a box. We even foolishly attempt to put our fellow sojourners in such boxes. I am tickled to say that not only was LeRoy Fish too big of a man to fit into most physical boxes, so also was he nearly impossible to put into any conceptual box. LeRoy Fish was a man who did not fit in any box. I will miss him. I want to tell you of some memories of events that I experienced with LeRoy on a trip that he and I took to southeastern Oregon in June 1999. It was the last year of the Oregon Breeding Bird Atlas Project. Through LeRoy Fish, fall 1997. Photo/S.

    PALM BEACH DOLPHIN PROJECT FACT SHEET The Taras Oceanographic Foundation 5905 Stonewood Court - Jupiter, FL 33458 - (561-762-6473) [email protected] MAGNIFICENT FRIGATEBIRD Fregata magnificens CLASS: Aves ORDER: Suliformes FAMILY: Fregatidae GENUS: Fregata SPECIES: magnificens A long-winged, fork-tailed bird of tropical oceans, the Magnificent Frigatebird is an agile flier that snatches food off the surface of the ocean and steals food from other birds. It breeds mostly south of the United States, but wanders northward along the coasts during nonbreeding season. Physical Appearance: Frigate birds are the only seabirds where the male and female look strikingly different. All have pre- dominantly black plumage, long, deeply forked tails and long hooked bills. Females have white underbellies and males have a distinctive red throat pouch, which they inflate during the breeding season to attract females Their wings are long and pointed and can span up to 2.3 meters (7.5 ft), the largest wing area to body weight ratio of any bird. These birds are about 35-45 inches ((89 to 114 cm) in length, and weight between 35 and 67 oz (1000-1900 g). The bones of frigate birds are markedly pneumatic (filled with air), making them very light and contribute only 5% to total body weight. The pectoral girdle (shoulder joint) is strong as its bones are fused. Habitat: Frigate birds are found across all tropical oceans. Breeding habitats include mangrove cays on coral reefs, and decidu- ous trees and bushes on dry islands. Feeding range while breeding includes shallow water within lagoons, coral reefs, and deep ocean out of sight of land.

    208 OREGON WILD Afterword JIM CALLAHAN One final paragraph of advice: do not burn yourselves out. Be as I am — a reluctant enthusiast.... a part-time crusader, a half-hearted fanatic. Save the other half of your- selves and your lives for pleasure and adventure. It is not enough to fight for the land; it is even more important to enjoy it. While you can. While it is still here. So get out there and hunt and fish and mess around with your friends, ramble out yonder and explore the forests, climb the mountains, bag the peaks, run the rivers, breathe deep of that yet sweet and lucid air, sit quietly for awhile and contemplate the precious still- ness, the lovely mysterious and awesome space. Enjoy yourselves, keep your brain in your head and your head firmly attached to the body, the body active and alive and I promise you this much: I promise you this one sweet victory over our enemies, over those desk-bound men with their hearts in a safe-deposit box and their eyes hypnotized by desk calculators. I promise you this: you will outlive the bastards. —Edward Abbey1 Edward Abbey. Ed, take it from another Ed, not only can wilderness lovers outlive wilderness opponents, we can also defeat them.

    RESPONSES TO HIGH TEMPERATURE IN NESTLING DOUBLE-CRESTED AND PELAGIC CORMORANTS ROBERT C. L^$IEWSKI AND GREGORY K. SNYDER ADULTand nestlingcormorants are often subjectto overheatingfrom insolationat the nest. Their generallydark plumage,exposed nest sites, and reradiation from surroundingrocks aggravate the thermal stress. Young nestlingsmust be shieldedfrom the sun by their parents. Older nestlingsand adults compensatefor heat gain throughbehavioral adjust- mentsand modulationof evaporativecooling by pantingand gular flutter- ing. This study was undertakento examinesome of the responsesto high temperaturein nestlingsof two speciesof cormorants,the Double-crested Cormorant,Phalacrocorax auritus, and the PelagicCormorant, P. pelagicus. The evaporative cooling responsesin birds have been studied in some detail in recent years (see Bartholomewet al., 1962; Lasiewski et al., 1966; Bartholomewet al., 1968; Calder and Schmidt-Nielsen,1968, for more detailed discussions),although much still remains to be learned. MATERIALS AND •VIETI-IODS The nestling cormorantsused in this study (four Phalacrocoraxpelagicus and four P. auritus) were captured from nests on rocky islands off the northwest coast of Washington. As their dates of hatchingwere not known it was impossibleto provide exact ages. From comparisonsof feather developmentwith descriptionsin the literature (Bent, 1922; Palmer, 1962), we judged that the pe'lagicuschicks were approximately 5, 5, 6, and 6 weeksold, while'the auritus chickswere 3.5, 3.5, 4.5, and 6 weeksof age upon capture. The nestlingswere taken to the laboratoriesat Friday Harbor, Washington on the day of capture and housed in three 4' X 4' X 4' chicken wire cages. The cageswere equippedwith plywood platforms for the birds to sit on and coveredon top and two sides to shield birds from wind and rain.
  • GREAT FRIGATEBIRD Fregata Minor

    GREAT FRIGATEBIRD Fregata Minor

    GREAT FRIGATEBIRD Fregata minor Other: ‘Iwa F.m. palmerstoni breeding visitor, indigenous Great Frigatebird is nearly a pantropical species, being absent only from the Atlantic Ocean north of the equator (King 1967, Harrison 1983, Marchant and Higgins 1990, Metz and Schreiber 2002). It is a common breeder at Johnston and Wake atolls (Amerson and Shelton 1976, Rauzon et al. 2008). In the Northwestern Islands it breeds in Mar-Oct, it roosts in large numbers on certain islets of the Southeastern Islands, and is a fairly common sight soaring over most islands (although less common over Hawai’i I) throughout the year. POBSP data indicate a slight depression in monthly counts during Nov-Feb, especially in the more northwestern of the islands; when not breeding, it appears to disperse widely throughout tropical and subtropical seas, with vagrants recorded N to California (CBRC 2007), and individuals banded at Kure recovered as far away as the Marshall and Philippine Is (Woodward 1972). Hadden (1941) records a large movement of birds from Midway toward Kure on 29 Dec 1938. A frigatebird, probably Great, is present in the fossil record of Ulupau Head, O'ahu, indicating presence in the islands for at least 200,000 years (James 1987). There was much confusion about the naming of frigatebirds in the 1800s. Early ornithologists in Hawaii (Isenbeck in Kittlitz 1834, Dole 1869, Stejneger 1888, Wilson and Evans 1899, Rothschild 1900) considered the Hawaiian population to be the same species as Ascension Island Frigatebird (F. aquila) of the c. Atlantic Ocean, although Cassin (1858) and Dole (1879) correctly assigned them to "palmerstoni" based on Gmelin's (1789) "Pelecanus palmerstoni" from Palmerston I in the Cook Is group.

  • The Genus Sula in the Carolinas: an Overview of the Phenology And

    h Gn Sl n th Crln: An Ovrv f th hnl nd trbtn f Gnnt nd b n th Sth Atlnt ht DAVID S. LEE and J. CHRISTOPHER HANEY Five of the eight recognized species of the genus Sula are known from the southeastern United States. Of these only the Northern Gannet (Sula bassana) occurs regularly in the Carolinas, but both the Masked Booby (S. dactylatra), formerly Blue- faced, and the Brown Booby (S. leucogaster) have been reported from North and South Carolina. Of the two remaining species, the Red-footed Booby (S. sula) is generally restricted to the Caribbean and disperses northward into the Florida Keys and Gulf of Mexico, whereas the Blue-footed Booby (S. nebouxii) is an eastern Pacific species with one accidental and astonishing record from south Padre Island, Texas (5 October 1976, photograph Amer. Birds 31:349-351). Generally the records for locally occurring Sula, excluding wintering Northern Gannets, are less than adequate as conclusive evidence of seasonal or geographical occurrence. Most problems result from confusing plumages of the various species and the general lack of experience of North American bird students with boobies. An additional problem is the fact that until very recently most ornithologists believed that boobies occurred off the south Atlantic states, outside Florida, only as rare accidentals, causing many records to be viewed with excessive caution and skepticism. Potter et al. (1980), for example, associated all records of boobies in the Carolinas with storms. In recent years few groups of birds have caused as many interpretive problems for the Carolina Bird Club's North Carolina Records Committee as have the Sula.
